Science in Sport Pro Water Bottle w/Easy Mixing | Yellow Squeeze Water Bottle w/Running Lockable Valve - 27 Fluid Ounce

Used these for the bike leg of an Ironman race. They fit in the bottle cages well and they are easy to open with you mouth while riding. The optic yellow makes it easy to spot your bike during transition which is a nice added bonus.

Good size and good quality.

I like the measurement markings on the sides of the bottle but the bottle leaks. I tightened the cap as tightly as it would go but the bottle still leaks. It even leaks in the verticle position, while the bottle is in the bottle cage. This is a big disappointment, especially with an SIS product. I I would have returned the bottles butmy return window was closed by the time I found out how cheaply made these bottles are.

It's just a water bottle.....bright

No the quality I was expecting to get

Quite a few peoples reviews say it leaks. I can see why however, if you screw the cap down tight enough and more importanly pull the spout out more than you think it should it dont leak. I discovered this after a few days of leaking all over me i noted the spout comes out double what you think as it clicks into what you think is open but it needs to go more.No more leaks. Great bottle

Es hat mir sehr gefallen 👍

De tacto comodo y facil de usar,muy flexible y comoda

Grande contenance et bonne resistance dans le temps. Très bien.

Impossible de boire dedans tellement l'odeur de plastique est forte....0/10
